Parts for your 2014 Toyota Crown-Camshaft sensor

2014 Toyota Crown camshaft sensor — what it does and how to look after it

Yes, the 2014 Toyota Crown does use a camshaft position sensor. Toyota’s technical literature for the S210-series Crown (Toyota TIS Repair Manual and the Electrical Wiring Diagram) shows camshaft position sensors on the 2.5L 4GR-FSE and 3.5L 2GR-FSE V6s, as well as the 2.5L hybrid 2AR-FSE four-cylinder. These manuals also list related fault codes (for example P0340/P0345 for camshaft position sensor circuits), confirming the sensor’s role in engine control. The Engine Control Module relies on camshaft “G” signals alongside the crank “NE” signal for sequential fuel injection, ignition timing and VVT-i operation.

On this Crown, the camshaft sensor keeps the engine perfectly in sync, telling the ECM exactly where each cam is so it can optimise spark, fuel and valve timing. That’s how you get smooth starts, tidy idle, crisp throttle response and proper emissions performance. Depending on the engine variant, there may be a sensor for each bank (V6) and often one per cam on the four-cylinder hybrid (intake and exhaust).

There’s no scheduled replacement interval in Toyota’s service guidance, but it’s smart to check the sensor and its connector during regular servicing—especially if there’s a check engine light with cam/crank correlation or cam sensor codes. Clean oil is key: sludge and varnish can upset VVT operation and create symptoms that look like a sensor fault.

• Common signs of trouble: longer cranking, rough idle, flat spots, poor fuel economy, and DTCs such as P0340, P0345 or cam/crank correlation codes.
• Quick checks under the bonnet: inspect the plug and wiring for oil intrusion, heat damage, or green/white corrosion, verify the sensor’s O-ring isn’t leaking.
• Basic replacement tips: disconnect the battery, remove any engine covers, unplug the connector, swap the sensor, lightly oil the new O-ring, refit and clear codes. Use a scan tool to confirm cam/crank sync and VVT response after a short road test.

If symptoms persist after replacement, follow Toyota’s diagnostic flow in the Crown repair manual: verify power, earth and signal at the sensor, check for timing chain stretch or misalignment, and confirm VVT oil control performance. Genuine or OE-quality sensors tend to give the most reliable results, and keeping to proper oil change intervals in Aussie and Kiwi conditions goes a long way to preventing repeat issues.

Popular questions about the 2014 Toyota Crown camshaft sensor

Where is the camshaft sensor on a 2014 Toyota Crown?
On the V6 engines it’s located at the front or top of each cylinder head, one per bank. On the 2.5L hybrid four-cylinder you’ll typically find sensors near the front of the cam cover, often one on the intake side and one on the exhaust side. Removing the plastic engine cover makes them easy to spot.

What symptoms point to a failing camshaft sensor?
Expect hard starting, uneven idle, hesitation, reduced power and a check engine light. Scans may show codes like P0340/P0345 or cam/crank correlation faults. Because VVT relies on accurate cam data, the engine may feel lazy or inconsistent when the sensor signal is weak or missing.

Should the camshaft sensor be replaced as routine maintenance?
No, there’s no routine interval. Replace it when diagnostics confirm it’s faulty. As part of normal servicing, inspect the connector and harness, keep to timely oil changes, and use the correct viscosity oil to support stable VVT operation and clean sensor readings.
